This study aimed to evaluate the clinical features, radiological findings, and surgical outcomes of ODS patients treated with endoscopic sinus surgery (ESS). Methods: This retrospective study included 139 patients diagnosed with ODS who underwent ESS. Demographic characteristics, clinical symptoms, radiological findings, and treatment outcomes were analyzed. Outcomes were assessed using pre- and postoperative LundKennedy (L-K) scores, with additional evaluation of the impact of concurrent dental treatment. Results: The most common etiology was periodontal disease (60.4%), followed by dental implants (20.1%) and dental extractions (19.4%). Radiological findings revealed sinus involvement beyond the maxillary sinus in 78.4% of patients, with common abnormalities including periapical abscesses (60.4%), oroantral fistulas (19.4%), and implant-related complications (20.1%). Patients who received concurrent dental treatment with ESS demonstrated significantly better outcomes, with success rates of 96.4% compared to 73.9% for those without dental treatment (p = 0.003). Conclusions: ODS is frequently underdiagnosed due to overlapping symptoms with chronic rhinosinusitis of other origins. Radiological imaging is crucial for identifying dental pathologies contributing to ODS. Combining ESS with dental treatment significantly improves outcomes and is recommended as the optimal management strategy for ODS.<\/jats:p>","DOI":"10.3390\/jcm14082821","type":"journal-article","created":{"date-parts":[[2025,4,20]],"date-time":"2025-04-20T20:24:16Z","timestamp":1745180656000},"page":"2821","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Clinical and Radiological Analysis of Odontogenic Sinusitis: A Retrospective Study"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5083-8720","authenticated-orcid":false,"given":"Shin Hyuk","family":"Yoo","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Dankook University College of Medicine, Cheonan 31151, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6015-7048","authenticated-orcid":false,"given":"Hahn Jin","family":"Jung","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Chungbuk National University Hospital, Chungbuk National University College of Medicine, Cheongju 28644, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5163-536X","authenticated-orcid":false,"given":"Soo Kyoung","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology-Head and Neck Surgery, Chungnam National University Sejong Hospital, Chungnam National University College of Medicine, Daejeon 34134, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji-Hun","family":"Mo","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Dankook University College of Medicine, Cheonan 31151, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,19]]},"reference":[{"key":"ref_1","first-page":"e70","article-title":"Meta-analysis of the etiology of odontogenic maxillary sinusitis","volume":"15","year":"2010","journal-title":"Med.
